Team India
Yahoo Finance23 July 2020
One of the most significant creations in the history of human kind is the concept of building bridges to provide passage, overcome obstacles, connect places and achieve progress as a society.
Humans have built some astonishing bridges around the world, either to make life easier or to enable nations to develop beyond imagination. Here’s a look at some of the longest bridges built in the history of mankind.
While no Indian bridges feature in this list, guess which country does house the majority of these bridges? Do you think India will soon be as efficient and high-tech as China to build such stupendous structures?
10) Line 1, Wuhan Metro Bridge
Length: 37,788 meters
Country: China
Completed in: 2009
The Line 1 of Wuhan Metro is an elevated metro line in the city of Wuhan, Hubei. It is the longest continuous metro viaduct in the world. Line 1 opened on 28 July 2004, making Wuhan the fifth city in mainland China to have a metro system after Beijing, Tianjin, Shanghai and Guangzhou. This is the first Metro line in China incorrectly referred to as a light rail line in Chinese terminology because it is elevated. Originally a branch line was planned to cross the Yangtze to Wuchang District via the Second Wuhan Yangtze River Bridge.
9) Lake Pontchartrain Causeway
Length: 38,442 meters
Country: United States
Completed in: 1956 (southbound), 1969 (northbound)

The longer of the two bridges is 23.83 miles (38.35 km) long. The southern terminus of the causeway is in Metairie, Louisiana, a suburb of New Orleans. The northern terminus is at Mandeville, Louisiana. Since 1969, it was listed by Guinness World Records as the longest bridge over water in the world; in 2011, in response to the opening of the longer Jiaozhou Bay Bridge in China, Guinness World Records created two categories for bridges over water: continuous and aggregate lengths over water. Lake Pontchartrain Causeway then became the longest bridge over water (continuous)[3] while Jiaozhou Bay Bridge the longest bridge over water (aggregate)
8) Beijing Grand Bridge
Length: 48,153 meters

The project forms part of the Kuwait National Development Plan 2035. The bridges are named after the late Sheikh Jaber Al-Sabah who reigned during the Gulf War. to commemorate his contribution to the development of Kuwait. It is one of the largest and most challenging transport infrastructure projects in Kuwait, as well as the entire Middle East region. The Main Link is the 4th longest road bridge in the world at 36.14 km. Both bridges have a combined length of 48.5 kilometers.

5) Weinan Weihe Grand Bridge
Length: 79,732 meters
Country: China
Completed in: 2008

The bridge was completed in 2008 but the railway line itself did not open until February 6, 2010.[2][3][4]
During construction of the Weinan Weihe Grand Bridge there were at least 10,000 workers 2,300,000cubic meters of concrete and 45,000 tons of steel

3. Tianjin Grand Bridge
Length: 113,700 meters
Country: China
Completed in: 2004
Tianjin Grand Bridge is a railway viaduct bridge that runs between Langfang and Qingxian, part of the Beijing–Shanghai High-Speed Railway.

At the time Guinness World Records recorded it as the second longest bridge in the world. The design of the elevated track was chosen on the one hand to avoid numerous individual structures for crossing roads and railways, and on the other to shorten the construction period. In addition, the railway line requires less land area in this design: a railway embankment requires 28.4 hectares per routed kilometer, the bridge but only 10.9 ha, less than half the area. The bridge consists of 32 m long box girders weighing 860 tons each. These girders were created in two workplaces along the bridge, brought to the installation site on the bridge section already installed, and then placed on the piers by a special crane.
2. Changhua–Kaohsiung Viaduct
Length: 157,317 meters
Country: Taiwan
Completed in: 2004

Completed in 2007, the bridge is 157,317m (516,132 ft) or 97.8 miles in length. The railway is built across a vast series of viaducts, as they were designed to be earthquake resistant to allow for trains to stop safely during a seismic event and for repairable damage following a maximum design earthquake. Bridges built over known fault lines were designed to survive fault movements without catastrophic damage.
